l My'present invention relates to certain new and useful improvements incondensers and more particularly? to surface condensers, the objectbeing to facilitate the condensaw tion of the steam and the removal bythe dry .vacuum system of the air and uncondensable vapors remainingafter the steam is condensed. Y The invention consists essentially in avsurface condenser having'a. spirallyshaped afa condensing chamber withthe steam enter- Ying at the large end of the spiral and the air anduncondensable vapors Withdrawn at its f small end; and the inventionalso comprises numerous details and peculiarities in the construction,arrangementand combination of parts substantially as Will be hereinafterdescribed and claimed. ln the accompanying drawing illustrating myinvention :-F igure l is a top plan view of my improved surfacecondenser. Fig. 2 is aside elevation of the same. Fig. 3 is a detail1view in partial section of the partition employed Within the condensershell -or forming the spiral condensing'chamber. Fig. el is an enlargedcrosssection on the line 4, 4, of Fig. 2. Fig. 5, is an enlargedcross-section on the line 5, 5 or" Fig.A Fig. 6 is a longitudinalsection on theline G, 6 of Fig. l.

Similar characters of reference designate corresponding parts throughoutall the ditferentfigures of the drawing.

l denotes the usual cylindrical shell of a surfacecondenser,l the sainehaving any, suitable dimensions and builtin any approved style. Ateneend 'of the shell l is a chamber 2 covering the entire head of theshell, While at the other end are two independent chambers 3 and 4. eachcovering one-half of the end of the shell and separated by Van inter-vvening partition Horizontal Water tubes 9 are located within the shell land extend between the end chambers 2,r31and e with which theycommunicate. Chamber 3 has a Water inlet 5 and chamber 4 has a Wateroutlet 6. The course of the Water, therefore, lsffrom the chamber 3through a part of the tubes 9 into the chamber 2, and then backfrom"`ehamber 2 through the rest of tubes 9 tothe chamber et havingoutlet 6. y

.On one side of the shell l, preferably at a point about midway of itslength, is an opening 7 for the admission of the exhaust steam,'saidopening being usually a large round opening and consisting of an inletpipe or sleeve cast integral with the shell l, which shell opposite thepipe 7 lis provided With vertical slots l2 to form/a vsort of gratingthrough which the steam passes into the interior of shell l, Where itcomes into contact with the Water-cooled tubes 9, and the steam enteringthrough pipe 7 strikes this grating and is deflected thereby in bothdirections into the steam space 20 and into the interior of the shell.-This grating consisting of slots l2 may eiitend'a greater or lessdistance throughout the steam space 20, but it -Will often be foundsullicient to have theslots only in the immediate neighborhood oftheoperiing 7. On the under side of the shell l are suitable openings,one or more, for the Withdrawal of the Water of condensation, as 13, 13,Where the condensed Water pumpco'nnections are made. Also, on the sideof the shell conti .uous to the eX- haust inlet 7, cast therewit andrunning. substantially the entire length of theshell, is an outer'wall'lwhich forms in the outer part of the shell, a steam inlet space asindicated atkQO in Fig. 4. 'It Will be further v noticed that this outerauxiliary Wall 14 carries air outlet openings 15, one or more aspreferred, to Which are connected the dry air pump whose function it isto remove air from 7the interior of the condenser shell. These openings15 do not communicate with' the space 20. but only with the small endthat in cmbiiiation With'fthe cylindrical:

shell; it forms a. spiralcharnber which is largest at the'end near theexhaust opening 7, and which narrows down to a small end whence the airis withdrawn. This partition plate 1l is eccentrcally placed in theshell l and in form has a fiat longitudinal part 21 which merges at itsinnerend into a curved part that approaches in shape'that of a cylinder,but by noticing the cross-secy tion in Fig. l it will be seen that whilethe shell l is a complete-cylinder the placing of this eccentric curvedplate 11 therenftpprovides a condenser chamber-which is curved and whichdecreases in size from alarge end t0 a rather small end. The arttion 11is shown in detail in Fig. 3 an in cross-section in Fig,v 7. It has anopening at 16 Which eXtends longitudinally along the side of the samebetween the two angular plates 17, so thatair entering the chamberinside of the partition l1 will pass in through the elongated opening 16as indicated -by the arrow in Fig. 3, thuslfiowing under the anguiarpartitions 17 andbeing directed thereby circuitously, as shownby thearrow in Fig. 3, over said partitions 17 and in opposite directions intothe ends of the interior of the space within partition 11. These ends'connect through narrow lchannels 18 with the air outlets 15. Theartition plate 11 is, furthermore, provided) at intervals along itsbottom with sealed drains 19 that allow the water of condensation fromthe interior of, the artition 11 and from the .condenser tubes a ovesaid partition to drain intothe bottom of they-main condenser.

, These drain pipes 19 are curved, as shown,

to forma water seal to prevent the direct entranceof the steam upwardinto the interior of the partition 11. Thus it will be se'en that in asense the-partition plate 11, which, with the cylindrical shell 1, formsa spiral condensing chamber, has itself a condensing andcooling functionwithin its inl terior chamber, and may be properly termed an auxiliarycondensing chamber forsome of the tubes 9 lie inside `of this auxiliarychamber, and' these tubes in this auxiliary chamber are cold tubes,since the partition 11 is above the center of the main condensingchamber where are the tubes that receive the coldest water from chamber.

- While the tubes- 9 that connect the` water chambers at the 'ends fofthe main shell 1 maybe said to occupy substantially the whole of thelinterior space within shell vv1, 1 itwillbe seen that they are omittedoppo-` site the horizontalpartition 8 between the cliamber'sv and 4, asthere .could be vno suitable attachment effected adjacent to vsaidpartition, and also I find it convenient toomit them along certainIlines so asfto furnish passages 10 leading from theexhaust'.

steam inlet around among the bank of tubes so that a larger volume ofsteam may iow quickly to .parts of the shell more remote from theexhaust inlet and thus a larger volume of steam be brought into contactinstantly with a larger number of tubes.

These spaces 10 thus permit quick and effective circulation andcondensation.

As the steam enters through the inlet 7 and steam space i2() and iiowsthence into' the condenser shellvl it will come into contact with thewater-cooled tubes 9, with a large number at first, and with a lessnumber as the steam progresses around through the spiral condensingchamber, until thesteam will finally reach the small' end of the spiral,I

by which time it will have practically all' been condensed. Thecross-section of the spiral obviously decreases in proportion to thecondensation of the steam, and at the- Although the exhaust opening 7 isshown'A arranged horizontally, I do notwisli to be confinedhto sucha'location'for it may be placed vertically or otherwisev as desired vbyleaving the relation of the various parts the same. It will thus befound Athat a'surface condenser having a spirally-shaped -shell 'withthe steam' entering at the large end perpendicular to thetubes and theair withdrawn at the small end, provides an economical and effectiveconstruction fora surface condenser which gives uniform-ly excellentresults. Such a. spiral main chamber combined with an auxiliary chamber,and air cooler at the vsmall end lof thespiral is an advantageousstructural feature. A.

Various changes in the construction an'd varrangement-of theparts may bemade' withc out exceeding the scope4 of my inventiomand I, therefore,reserve 'the liberty of` making all such changes as experience maydictate to be useful or necessary.
